Dispose of NiMH and alkaline batteries properly. Check with your local government for
disposal and recycling procedures.
Do not mix NiMH batteries and alkaline batteries in RUBY. Replace all batteries of the same
chemistry at the same time. Do not mix new batteries with old batteries. Failure to follow this
precaution can lead to battery failure or leakage. Risk of explosion is possible if batteries are
replaced with an incorrect type.
